found this site and thought it had some very good info.

Introduction to Turbocharging and Supercharging

 

Pretty nice read good find

 

yes, nice. WDRacing wrote that and is a definite source of good info. However, I wouln't call that article "Introduction to turbocharging and supercharging". That article was all about turbocharging. Within a few lines of the article they say trubocharging is the best and leaves discussing supercharging behind. WDRacing is a turbo lover and wrote a good informative turbo article.
